Our bodies are as unique and varied as our personalities, and sometimes it can be a bit intimidating to try to find the perfect cup for your body. One of the most important factors to consider when you choose a menstrual cup is your cervix height.

How do you measure your cervix for a menstrual cup?

The first step to choosing a cup is measuring your cervix. The position of your cervix can affect how your cup fits and feels when you’re wearing it. We believe your menstrual cup should always be comfortable — it’s one of the biggest reasons for switching to a cup! If your cup is uncomfortable for any reason, your cup may be the wrong size or it may be positioned incorrectly. This is common for women who have a tilted uterus or a low cervix.

How do you know if your cervix is high or low?

How do you know if your cervix is high, low, or somewhere in between? We have an easy test to figure out your cervix height. All you have to do is insert your finger into the vaginal opening and feel for the cervix. Your cervix, which is the lowest part of the uterus, may feel like the tip of your nose: firm but a little soft. You may also feel a small dip in the middle, which is the cervical opening.

One important thing to remember is that your cervix changes position and texture throughout your cycle. Around ovulation or the middle of your cycle, the cervix becomes higher, softer, and harder to reach. During menstruation, the cervix is lower and firmer. Because this is when you’ll be wearing your menstrual cup, it’s best to check your cervix on or right before the first day of your period. (Measure your cervix in the shower to avoid any mess!)

Start with clean hands and trim nails and get into position. You may find it best to squat, or stand with one foot on the edge of the bathtub. Insert one or two fingers into the vagina and feel for the cervix.

If you can reach the cervix at just your first knuckle, your cervix is low. If you can reach it at the second knuckle of your finger, your cervix is a normal height. If your cervix is difficult to reach, or you cannot reach your cervix at all, you have a high cervix.

Once you know your cervix height, it’s time to choose your cup! We have different cups for all cervix heights from low to high. You want a cup that’s big enough to accommodate your flow, but not so big that it won’t fully open or it becomes uncomfortable.

Best menstrual cup for a low cervix

If your cervix is medium to low, we recommend that you start with our small Pixie Cup. Cup users with a low cervix may feel some discomfort if their cup rubs up against the cervix, so try a smaller or shorter cup. Our Slim Pixie Cups were made especially for users with a low cervix. They’re made with a slightly softer material, and they also have a shorter stem.

Low cervix tip: trim the stem

Stem length can also be an issue for those with a low cervix. If you find that the stem is irritating because it sticks out a bit, there’s an easy way to fix that, too!

If the stem of your Pixie Cup is protruding from your vagina, or if it irritates you inside, take some scissors and trim it just a little. Trim just a small amount at first, to make sure it’s not too short to reach for removal, and see if that works. Some women end up removing the stem entirely. This may work for you if your cervix is low enough that you can grab the cup and pinch the base to remove it without using the stem.

If the end of the stem is sharp after trimming, you can use a nail file to soften the edges. If you trim the stem and the bottom of the cup is still irritating, you can also try turning the cup inside out.

If you have a high cervix, we advise you to try our large Pixie Cup or even our XL Pixie Cup, depending on how heavy your flow is. Our large cups are taller, so they’re easier to reach if your cervix is high.

Choosing the best menstrual cup

There are several other factors to consider when choosing a menstrual cup, such as your flow, whether you’ve delivered babies, and the position of your uterus. Before making a final decision, read our blog on how to choose the right menstrual cup for you. You can also take our menstrual cup quiz!
